I've been stealing parts from my previous RR kits. First the super light ring wrench for the rear axle nut, along with the handle/adapter/socket wrench. Then two 10/13 mm wrenches for chain adjustment. Spare fuses. H7 bulb just in case. T25 and T30 drivers, can't remember which toolkit they came from. 17mm hex for left side of front axle, nobody seems to have one of those. Tire plug kit and mini compressor. That's it for me, all other stuff I might need I borrow or buy.
